What Harlequin looks like

Cream/white lateral pattern

Concentrates dorsal pattern into flame-like or high-contrast patches. Heterozygous animals show intermediate pattern concentration; homozygous show maximum concentration and contrast. Interacts with Tiger to create visible pattern breaks and "portholes." Antagonistic with Empty Back.

How to identify it: Harlequin animals show concentrated pattern flames, especially on dorsum. Super Harlequin shows maximum flame concentration.

How Harlequin is inherited

Harlequin follows a incomplete dominant inheritance pattern, carried on the Harlequin allele (locus HQ).
